Background
Objective: To determine if a fluid overload of less than 10% of body weight and early initiation (<12 hours ) of RRT behave as an independent prognostic factor for mortality in patients with AKI KDIGO 3 in the ICU.
Methods
Retrospective cohort study that included patients hospitalized in the ICU of a hospital in Medellín-Colombia with a diagnosis of AKI KDIGO 3 and need for RRT.
Results
278 patients with a median age of 63 years, 58.6% (163) men and 60.4% (168) diagnosed with sepsis were included. 166 (59.7%) were classified as early RRT and 112 (40.3%) as late RRT. The cumulative fluid balance was 9565 ml and 7496 ml, respectively. Mortality was 69% (192), with no significant differences according to the time of RRT (67 vs. 71%). There were no statistically significant differences between the early and late therapy group (OR adjusted 1.34, 0.65-2.75); nor in those with a percentage of accumulated fluid balance greater than 10% of body weight (OR adjusted 1.27; CI 0.73-2.23).
Conclusion
Early initiation of RRT, less than 12 hours from diagnosis, and with an accumulated fluid balance of less than 10% of body weight, did not have a lower risk of in-hospital mortality in patients with AKI KDIGO 3 in the ICU.
